General tips:
- Untill you learn the ropes, Warrior and Dark Knight are easier to tank with when it comes to AoE tanking.
- If you level Arcanist, you will unlock SCH and SMN, so if you want to heal and get another dps to max level, level Arcanist.
- When healing, if you want to have a easier time healing, go WHM.
- Tanks need Provoke/Rampart/Flash and other defensive skills. Healers need Swift Cast (THM skill) and Protect/Stoneskin/Cleric Stance (CNJ).
- When tanking expect alot of players resisting your leadership, they will pull or ignore marks. You will fail alot, but this is part of the learning proces.

Tank tips:
- Always use defensive skills when they are on a cooldown, wasting them is pointless.
- Always make sure the mobs face away from the group.
- When having issues with keeping agro, do not be afraid and ask players to use CC and Mark the mobs for easier agro management.
- Eat food that increases STR and VIT
- Put all your stat points into VIT
- Learn to rotate between agro building skills and the ones that give debuff/buffs to the tank and mobs.

Healer tips:
- Use the cooldowns like Rouse, Divine Seal etc.
- Learn to know when to use Eos or Selene, the same can also be said for AST cards, learn what they do and which card should be used for which class. Using Ewer for example on DRK is pointless, since Darkside negates the effect.
- Speak up and tell the tank to grab more or less, if you dont say anything, nothing will happen.
- Learn to control the pets, untill level 50 you can keep her on auto, but learning to control her at lower level will make it easier for you.
- When you have more then 80% mana and you know that it will stay like this, put on Cleric Stance and help the group by dealing damage.
- Put all your stat points into Mind.
- Same with tank, when leveling make sure you eat food with mind, piety and spell speed etc.

I hope these were usefull.
